Arguments
boot_device
A device path or list of devices from which the firmware attempts to boot, or
a saved boot specification in the form of an environment variable. Use the set
command with the environment variable BOOTDEF_DEV to define the default
boot device. You can specify a list of devices by using commas without spaces.
For example:
>>> set BOOTDEF_DEV ewa0,dka0

the environment variable BOOT_FILE to specify a default boot file.
-flags longword [, longword ]
Specifies additional information to the operating system.

image is loaded and page tables and other data structures are set up. Console
device drivers are not shut down when you specify this option.
